If a current of $1.6 \, mA$ is flowing in a conducting wire,then the number of electrons flowing per second is:

Given a current-carrying wire of non-uniform cross-section,which of the following is constant throughout the length of the wire?

The current passing through a copper voltameter is $3.2 \ A$. The number of copper ions $(Cu^{2+})$ deposited at the cathode per minute is:

The current in a conductor varies with time $t$ as $I = 2t + 3t^2$,where $I$ is in ampere and $t$ is in seconds. The electric charge flowing through a section of the conductor during $t = 2 \, s$ to $t = 3 \, s$ is ............. $C$.

$A$ current of $20\,\mu A$ flows for $30$ seconds in a wire. The total charge transferred will be:

The current $I$ versus time $t$ graph for a conductor is shown in the figure. The average current through the conductor in the interval $0$ to $15 \, s$ is ............ $A$.
